LimbusZero

Custom Microcontroller Board based on STM32C0-Series

Features

• STM32C031K6T6 Microcontroller
• ST M24C01 I2C EEPROM
• no crystal oscillator since this board uses STM32 build in 48MHz HSI48RC clock generator
  • accuracy needs to be discussed but since software is working fine I guess there will be no dramatic issus
• Power indicator LED
• USB mini as power supply NO DATA!
• User LED
• 2.54mm Pin Headers that would fit on regular breadbords for rapid prototyping
• debug / programming interface according to STLink that comes with most of STM32 Nucleo Boards

Firmware

There is quite extensive demo I developed for Emil's Birthday using the breadbord-IO and a neopixel ring in the software sub folder. It's written in C and uses the STM32-HAL and STM32-cubeIDE. Look closely, main-loop is empty since all features and peripherals are controlled by interrupts so the user section while(1){} remains untouched.
